As the title says already - another approach to LW-COM -
hopefully simple(r) to understand, because:
- it doesn't require to implement "all the Methods in the *.bas-Module"
- instead, method-implementation remains in the Class-CodeFile
- only the 3 Members of the IUnknown-interface will be swapped
On 32Bit, the minimal Class-Instance-size is only 8Bytes (half the size of a Variant).
Userdefined Private-Variables (when added to the two default-instance-members),
will increase the mem-usage from these 8Bytes obviously...
Performance (especially on instance-teardown) is as nice as one would expect from an lw-approach...
I've commented quite a bit, so there's more explanations in the code-modules.
Here's the Zip: SimpleLightWeightObjects.zip
Have fun,
Olaf
